This command will be sent by adbd to notify the client that the
connection will be over TLS.
When client connects, it will send the CNXN packet, as usual. If the
server connection has TLS enabled, it will send the A_STLS packet
(regardless of whether auth is required). At this point, the client's
only valid response is to send a A_STLS packet. Once both sides have
exchanged the A_STLS packet, both will start the TLS handshake.
If auth is required, then the client will receive a CertificateRequest
with a list of known public keys (SHA256 hash) that it can use in its
certificate. Otherwise, the list will be empty and the client can assume
that either any key will work, or none will work.
If the handshake was successful, the server will send the CNXN packet
and the usual adb protocol is resumed over TLS. If the handshake failed,
both sides will disconnect, as there's no point to retry because the
server's known keys have already been communicated.

Test: WIP; will add to adb_test.py/adb_device.py.
Enable wireless debugging in the Settings, then 'adb connect
<ip>:<port>'. Connection should succeed if key is in keystore. Used
wireshark to check for packet encryption.

If we have multiple keys available for authentication (ADB_VENDOR_KEYS
+ the one in ~/.android), we will still have keys in our list of
avilable keys after we've successfully connected. A subsequent
reconnection will start authorizing using the list of keys after the
key that actually worked, resulting in that session being unauthorized
until another reconnection happens. Clear the key list before
reconnecting to fix this. (We could do this after successfully
connecting, but we need to do this before reconnecting anyway, because
our connection could have died during authorization.)

* changes:
adbd: implement a nonblocking USB Connection.
adbd: rename daemon/usb.cpp to daemon/usb_legacy.cpp.
adbd: open functionfs ep0 as O_RDWR.
adbd: extract functionfs fd creation.
Implement a Connection that implements a nonblocking interface to
functionfs, to replace the existing implementation that uses two
threads that loop and call read and write respectively. The existing
implementation is vulnerable to a race condition that can occur when a
connection is terminated, where one thread can notice failure and
complete reinitialization of the USB endpoints before the other thread
noticed anything went wrong, resulting in either the first packet
coming from the other end disappearing in to the void, or the other end
getting a packet of garbage.
As a side benefit, this improves performance on walleye from:

Let's use LOG(FATAL)/PLOG(FATAL) for actual fatal stuff.
Add a Windows error(3) and move folks who didn't really mean "abort"
fatal over to it. Also get rid of syntax_error which wasn't adding a
lot of value, and most of the places it was adding "usage: " didn't seem
entirely appropriate anyway.
In particular, we seemed to have confused fastdeploy.cpp into aborting
in most user error cases, and none of the reviewers noticed. Clearly
we'd all lost track of far too many options.
(I've also cleaned up a few random instances of fprintf(3) + exit(2).)

Previously, when a TCP connection was disconnected from adbd, we were
registering it with ReconnectHandler, which led to the transport
sticking around after the socket was closed. Due to the naming of
TCP transports in adbd (host-<fd number>), this results in incoming
connections being immediately closed if their file descriptor number
ends up being the same as a TCP transport that had previously
disconnected.
Guard all of the reconnect logic with ADB_HOST, to fix this.

Most disconnects we're likely to encounter are cases where either we
notice immediately and can start reconnecting almost immediately (adbd
restarting because of `adb root`, etc.), or where we won't notice for a
while anyway, so a 10 second sleep is somewhat meaningless.

libstdc++ implements wait_until by calculating the offset between its
default clock and the clock that it's given by calling now() on each
and subtracting, and then adds that offset to the time_point argument.
When time_point::max is used, this overflows, resulting in the
reconnection thread spinning.

Add two states: connecting and authorizing, to disambiguate the offline
and unauthorized states, respectively.
Previously, devices would transition as follows:
offline -> unauthorized -> offline -> online
offline -> unauthorized (when actually unauthorized)
With this patch:
connecting -> authorizing -> online
connecting -> authorizing -> unauthorized (when actually unauthorized)
This allows test automation and the like to distinguish between offline
devices, unauthorized devices, and working devices without having to
do retry loops with arbitrary sleeps on their end.

This change is in preparation to allow the TCP-based transports to be
able to reconnect. This is needed because multiple threads can access
the Connection object. It used to be safe to do because one instance of
atransport would have the same Connection instance throughout its
lifetime, but now it is possible to replace the Connection instance,
which could cause threads that were attempting to Write to an
atransport* to use-after-free the Connection instance.

This change adds a callback that is invoked exactly once, either when
the connection is fully established (i.e. CNXN packets have been sent
and received) or the atransport object is deleted before that (because
the connection failed).
This helps in distinguishing between successful and failing connections
for TCP. Especially when there is some kind of port
forwarding/multiplexing in between (like an SSH tunnel or SSLH proxy).
